Outbound, without and with Propel.
You take the conversations. Everything before them stops eating your week, and nothing goes out that you did not read.
| Job | Without Propel | With Propel |

| The list | An export, half of it stale. | One sentence, turned into an Apollo search with your own key. People already on your list are skipped.How |
| The email | A template, or a model rewriting every copy where nobody reads it. | One email you approve, filled in for each person from a fixed set of fields. No copy says anything you did not read.How |
| Every copy | Sent without a second look. | Checked again before it sends. A banned word or a number nothing backs stops that copy.How |
| Your domain | A blast that risks it. | Your own mailbox, up to 30 a day by default, and a one-click unsubscribe in every email.How |
| Replies | An inbox to dig through. | Sorted: interested, a question about price, pushing back, not now, or stop. Your booking link is ready.How |

Your domain stays healthy.
You approve every campaign at first, and at most it can reach "it posts unless you stop it". It never sends fully on its own, because your domain is on the line.
Limits read from the product, 12 November 2026 Every limit, explainedAlways waits for you
- The email itself: every campaign starts from one you approve
- Anything that spends money
Never
- Writing to people found through GitHub
- Writing again to someone who said stop
- Changing an approved email for one person beyond its fields
Can earn more freedom
- Cold emailup to: It posts unless you stop it
- Follow-upsup to: It posts unless you stop it
Each channel starts at "It drafts, you approve" and steps up only on results. One bad claim drops it straight back.
What do sales and growth teams ask?
Where do the leads come from?
From Apollo, through your own Apollo key. Describe who your product is for in a sentence and Propel turns it into a search, skipping people already on your list. You can also import your own list.
Does it write a new email for every person?
No, on purpose. You approve one email, and Propel fills it in for each person from a fixed set of fields: first name, company, role and a few more. Every copy is checked again before it sends, so nobody receives a sentence you never read.
Does it send without my approval?
Not at first. Cold email starts by waiting for your yes on everything, and even once it has earned more freedom it goes no further than "it posts unless you stop it".
Whose mailbox does it send from?
Yours, at a pace that keeps your domain healthy, with a one-click unsubscribe in every email and bounces suppressed automatically.
What happens when someone says stop?
It marks the reply as a stop and writes to them no more. Interested replies get your booking link ready instead.
Does it send LinkedIn messages?
Not from your account yet. LinkedIn messages from your own account are coming; for now Propel works through your mailbox.
